Perfect climate for travelling

Airports are huge complexes with many and diverse requirements on ventilation

and air conditioning. They are 'places of public assembly' and hence subject

to safety regulations that ensure sufficient fresh air by mechanical ventilation

and air conditioning systems. In the event of a fire, such systems also aid in

the mechanical smoke extract in order to keep escape routes free from smoke.

Air conditioning system solutions for the entire complex. As a system supplier, TROX offers the broadest spectrum of ventilation and

air conditioning components, from air handling units, fire dampers and tunnel

dampers to air terminal devices and air-water systems, and to control components

and systems, providing specialist consultants with a multitude of options for

complete airport solutions. Today, and in fact more than ever before, the focal

point of air conditioning system design is energy efficiency. TROX has long been

committed to the development of adaptable high-efficiency system solutions

that help not only to save resources but also to reduce operating costs.

The highest safety standards due to innovative fire protection and smoke extract technology. TROX has always provided important input to innovative solutions and been at the

forefront of developing and enhancing fire and smoke protection as well as control

systems, which are immensely important particularly at airports. Fire tests to

determine the fire protection classification of building products for ventilation and

air conditioning systems in accordance with national and international standards

are regularly carried out in the TROX International Center for Fire Protection (ICB),

which is the most modern of its kind.

Perfect air conditioning for airports:

• comprehensive and integrated with the central BMS

• adaptable and efficient

• reliable and safe

Whatever your destination, chances are that TROX is already there. In many

airports around the world, TROX products ensure well-being and safety for staff

and passengers alike: with German engineering at its best!

TROX components and systems are installed at airports on all five continents.

Whether international transport hubs such as New York JFK, Frankfurt, Singapore

or Dubai, or domestic airports in other countries such as Australia, Ireland, Poland,

Switzerland, Hungary, Austria, Greece or Brazil: Ventilation and air conditioning

components and, even more importantly, innovative and proven fire protection

and smoke control technology from TROX can be found at numerous airports all over

the world. TROX has also developed individual solutions. The jet nozzles at Madrid

Barajas, for example, blend in perfectly with the terminal's characteristic architecture

by star architects Rogers and Estudio Lamela.

This application brochure is dedicated to the most critical ventilation and air

conditioning issues that airports face these days. The main focus is on airport

terminal ventilation, control, and fire and smoke protection. The requirements

on air in the office buildings, restaurants, and shops at an airport are no

different from those of other buildings where people go for work or leisure.

Cosmopolitan air

The load requirements in an airport terminal vary. As a consequence, flexible

air conditioning is in demand, creating a complex challenge for designers and

specialist consultants. Most terminal buildings are unusually high and comprise

diverse functional areas as well as stationary workplaces to which the comfort

criteria for workplaces as stipulated in regulations and directives apply. It is

therefore possible to create a so-called micro climate in the area where the

ground staff works – a micro climate with its own air supply and individual

heating or cooling systems.

Other aspects that need attention are related to the specific use of an airport

terminal. Load requirements fluctuate and may be extreme – throughout a day

but also depending on the season. High levels of comfort for passengers and staff

can only be achieved with unconventional air handling concepts. The various

Ready for take-off

Ready for take-off

Airports have their own aerodynamics.

Airport terminals constitute probably the most challenging task for specialist consultants.

On the following pages we describe some alternative approaches and deal with the vital role

of intelligent control systems and of safe fire protection and smoke extract technology.

11

Airport air All-air system: mixed flow

Good air quality in a terminal building can be achieved only with a sufficient

fresh air flow rate that is based on the number of occupants. With a classic all-air

system one would need a specific supply air flow rate of 6.0 to 20.0 m³/(h m²).

The required temperature is generally provided by the supply air. In the highest

areas of the departure and arrival halls, air is usually supplied with either

actuator-driven or self-powered jet nozzles.

In functional areas with a clear height of up to 6.0 m, fresh air is supplied with

adjustable swirl diffusers or other ceiling diffusers. Mixed flow ventilation means

that supply air and room air mix evenly such that a uniform temperature and air

distribution is quickly achieved. Sophisticated air terminal devices with specific

blade contours ensure that high airflow velocities and temperature differences

are quickly reduced.

Variant: Mixed flow ventilation with jet nozzlesOccupied zone: airflow velocity near the ground - Sitting areas and workstations < 0.2 m/s

- Free jet entry area (should not be used for workstations) < 0.5 m/s

Supply air temperature – mixed flow 16 to 18   °C

Proportional cooling capacity in case of mixed flow up to 80 W/m²

The adjustable TJN jet nozzles are made of high-grade polymer and allow for adapting the supply air flow to different conditions. The enhanced jet nozzles

are acoustically optimised and more energy-efficient than similiar products since

the actuator is fitted on the outside and does not lead to any additional pressure

drop.

VDL swirl diffusers are suitable for large volume flow rate ranges and can be adjusted mechanically or manually. Blade adjustment allows for optimum

ventilation (purging) of the occupied zone while high comfort requirements

are met at the same time.

The stand-alone LON-WA TDC module is used for the control of adjustable air terminal devices independent of the temperature; it can be integrated

with a central BMS easily and flexibly.

AIRNAMIC swirl diffusers are fitted with innovative air distribution elements that combine an extremely quiet air discharge with the optimum swirl. The most

demanding comfort requirements can thus be met, even with very high volume

flow rates.

PASSCLEAN ceiling diffusers are ideal for departure halls with their high passenger volumes. With PASSCLEAN diffusers, contamination of the ceiling

is avoided in spite of the high secondary air induction.

Airport air All-air system: displacement flow

Displacement flow systems may be combined with mixed flow systems; they can

also be used for situations where small or medium air volumes are required and

where only smaller heat loads (e.g. from people or equipment) must be dissipated.

If necessary, additional passive cooling systems may be used.

Displacement flow systems are ideal in places where maximum comfort is required,

e.g. for the airport staff. Low airflow velocities help to keep workplaces free from

turbulence while ensuring high room air quality.

Variant: Displacement flow combined with large area heating and cooling systems, e.g. chilled ceilings Airflow velocity - Occupied zone, sitting areas and workstations < 0.2 m/s

- Near zone of displacement flow diffusers (within 5 m) < 0.5 m/s

Supply air temperature with displacement flow ventilation 20 to 22 °C

Proportional cooling capacity by supply air 20 to 40 W/m²

Extract air temperature near the roof up to 32 °C

TROX displacement flow diffusers are available for many different installation

situations and in a multitude of forms and appealing designs; they can be

aesthetically integrated into existing architectural designs. In fact, special

designs have been produced for several airports.

Displacement flow ventilation requires that the supply air temperature is lower

than the room temperature. Displacement flow diffusers, which should be installed

as close to the floor as possible, supply air to the room such that a supply air pool

is created. The convection from people and other heat sources causes the air in

this supply air pool to rise. The extract air is then removed above the occupied

zone, ideally near the roof.

The QL displacement flow diffusers with their special air distribution nozzles are characterised by an excellent, uniform velocity profile and a smaller near zone.

Airport air Air-water systems

More and more air-water systems are employed today since the heating and cooling

capacity of these systems can be provided independent of the required fresh air

flow rate. Various types can be distinguished:

• large-area heating and cooling systems, e.g. chilled ceilings,

combined with displacement flow systems

• passive chilled beams combined with mixed flow systems

• active chilled beams

Air-water systems have the advantage that the thermal energy is very efficiently

transported by water – rather than by air. This means that less energy is required

to provide the same heating or cooling capacity. In the airport areas with offices,

shops and restaurants, thermal loads are ideally dissipated by water side heating

and cooling systems.

Air-water systems are suitable for the ventilation of functional areas with an

average required fresh air volume of up to 12 m³/(h m²). For areas with a very high

occupancy, such as security, an additional system can provide up to 20 m³/(h m²).

The DID 632 active chilled beam offers comfortable ventilation and air conditioning for rooms with a high heat load. The aerodynamic properties of ceiling diffusers in

combination with the energy-efficient dissipation of heat loads using water make

active chilled beams the perfect solution for sustainable architectural concepts.

PKV passive chilled beams (no supply air) are used to dissipate high interior heat loads, thereby fully achieving the energy benefits of dissipating loads with

water.

TROX air-water systems allow for the space-saving integration of additional components such as lighting, smoke detectors, loudspeakers or sprinklers. Air-water

systems may be designed as canopies, for example, to accentuate a building's

architecture, or blend in inconspicuously with the ceiling construction. All systems

can be integrated with the central BMS.

Fire prevention

Airports are complex buildings. Huge quantities of air are supplied to and extracted

from an airport terminal. In the event of a fire, adjacent areas such as shopping

zones must be closed off from the departure hall. Underground car parks present,

due to their low ceiling, a particular challenge for smoke extract systems. Following

the devastating fire at Düsseldorf airport in 1996, airports all over the world have

examined and modernised their smoke control and smoke exhaust systems. Düsseldorf

International is today one of the most modern and safe airports with regard to fire and

smoke protection.

The prime objectives of fire and smoke protection are as follows:

• Ensure the safety of people

• Support the firefighters in extinguishing the fire and in rescuing people

• Ensure the safety of buildings and equipment (keep disruption of operations

to a minimum)

For these objectives to be achieved, modern smoke extract management

for complex buildings must fulfil a multitude of tasks:

• A fire must be detected, and an alarm emitted, at an early stage – even if

the temperature remains comparatively low, e.g. in case of a smouldering fire.

• The smoke extract system must be automatically triggered at an early stage

to give the people in a building sufficient time to escape.

• Spread of the fire and transmission of smoke to adjacent occupied zones

must be prevented, e.g. by a mechanical smoke exhaust system.

• Positive pressure must be maintained in corridors, stairwells, and escape

and rescue routes; pressurisation systems must be installed.

• Escape routes must allow passengers and staff to safely escape as quickly

as possible.

• In the event of a fire, elevators must be made to stop only on floors where

no smoke has been detected.

21

A mechanical smoke exhaust system ensures a smoke-free layer with a height of at least 2.50 m, extending the time available for escape; this is essential for large indoor spaces such as departure halls, atria, or conference rooms.

Fire protection: tested, CE-certified and with building inspectorate approval

Large airports offer many applications for TROX smoke extract systems. Our smoke

extract components and systems are the basis for effective smoke extract management.

With such safety-relevant systems, components from a single source are the best

solution for critical interfaces.

Our fire dampers and smoke extract dampers as well as the X-FANS smoke exhaust

fans have been certified to EN standards and approved by the building inspectorate

in Germany for many applications. TROX engineers are experts in their fields and

always apply the latest findings from both TROX fire tests and tests by independent

testing institutes to the design; as members of standardisation committees they

also provide valuable input to these bodies.

Intelligence inside. TROX fire engineering products.

Fire dampers must close at a certain temperature or when smoke is detected. They effectively close off adjacent fire compartments and prevent the spread

of fire and smoke.

TROXNETCOM communication systems for AS-i or LON, and with Modbus or BACnet interface, ensure the seamless integration of TROX fire protection and

smoke extract components with central building management systems. In airports,

which are frequented by many passengers with restricted mobility, complete system

solutions for fire protection are indispensable. They ensure that a fire is detected

at an early stage and prevented from spreading; they also ensure the smooth

escape of people and the evacuation of buildings. TROXNETCOM offers solutions

that are SIL2-certified and provide overall safety even in case of a malfunction.

TROX smoke detectors of Types RM-O-VS-D-LON/RM-O-3-D detect smoke in ducts at an early stage and independent of the temperature, and they release the fire

dampers such that they close. The detectors are fitted with comprehensive

self-monitoring functions (contamination, airflow, electronics) and require

maintenance only once per year.

Infrared sensors and emitters on the walls of the Düsseldorf airport departure hall – at 5 m from the ground and with a distance of less than one metre from each other – detect smoke immediately

and trigger an alarm. The axial fans under the ceiling start working at once to extract the smoke.

24

Smoke is in the airX-FANS smoke exhaust systems

In complex buildings, such as departure halls, smouldering fires can easily have

devastating effects if they are not immediately detected. Mechanical smoke

exhaust systems can provide a higher level of safety than other systems. They

create smoke-free layers along the escape and rescue routes and therefore allow

people in the building to escape by themselves. Smoke exhaust fans remove

smoke gases, thus preventing smoke from spreading uncontrollably and supporting

the firefighters in extinguishing the fire.

Mechanical pressurised smoke exhaust systems remove not only smoke but also

dissipate the heat, thus preventing a dangerous flash over. The required air

transfer dampers open at the same time.

Requirements of a pressurisation system.Keeping the layer with smoke gases separate from the smoke-free layer requires

a delicate combination of supply and extract air; the following conditions must

be met in particular:

• At the boundary between the smoke gas layer and the smoke-free layer, only minimal

horizontal and vertical airflows at low velocities should be present, if at all.

• Supply air openings must be adequately sized and be installed at the right

distance from each other. They must open automatically before the smoke exhaust

fans are switched on.

• Supply air must be discharged into the smoke compartment considerably below

the layer with smoke gas, ideally with no or very little impulse, and at a low

velocity (

Smoke exhaust in underground car parks Danger lurks below the surface

Cars catching fire in underground car parks are more common than one should

think. A car catching fire in a car park under an airport terminal poses

a particularly high safety risk. The real danger, however, are the highly

poisonous smoke gases.

Smoke extract via the ductwork. The first and foremost task of extract air systems is removing the exhaust fumes

through extract air ducts while fresh air is led into the garage via ventilation

ducts or other openings such as the access slope. The heart of such a system

is a two-stage axial fan. In the event of a fire, the second axial fan for smoke

exhaust is automatically switched on.

The smoke gases rise towards the ceiling from where they are removed through

duct systems. Creating different layers is usually not possible in underground

car parks because of the lack of height.

Keeping spaces smoke-free with a jet ventilation system (JVS).Jet ventilation systems are an alternative to conventional smoke exhaust

systems. When in ventilation mode, the combined effect of radiation and

induction of the jet ventilation fan ensures a particularly efficient mixing

of air, the removal of CO gases and hence fresh air in the underground car park.

The volume flows calculated for the car park are created by fans installed in

the central shafts and are directed towards the outside; dedicated extract air

and smoke extract ducts are not required.

In the event of a fire, the smoke gas temperature increases, and the gases rise

towards the ceiling, where they spread. If smoke is detected, the fans, which are

installed in the extract air ducts, are switched on and remove the smoke from

under the ceiling. At the beginning, a layer is created which is nearly free from

smoke. Escape and rescue routes are hence easy to recognise and allow people

to leave the building.

The jet ventilation fans are only switched on after about three to five minutes.

By that time, the people will have left the underground car park via the short

escape routes. The jet ventilation fans dissolve the smoke layers in the previously

selected areas, and 'dead corners' are being cleared. The firefighters can now

locate and eventually extinguish the fire without being obstructed.

The jet ventilation system allows for large fire compartments so that underground

car parks can be designed accordingly – open, spacious, and pleasant. Users will

welcome the additional ease of orientation, feel better, feel safer – and are

indeed safer in such a garage.

Jet ventilation fans are used for the ventilation and smoke exhaust in underground car parks.

The functional areas of an airport are usually divided into different 'control zones'. Volume flow controllers react to the air quality and adapt the volume flow rate for every zone separately and based on demand, while frequency converters control the fan speed, again based on demand. This saves valuable energy and reduces the 'air transport cost' considerably.

X-CUBE air handling units are extremely variable and adaptable to different control strategies and room conditions.

Air management: handling and conditioning airflows

For an airport with its different buildings and areas, air handling units have to be

highly variable and provide utmost adaptability to each control strategy. Flexibility

with regard to the installation is an advantage since the units have to be adapted

to different locations and conditions.

The air around an airport terminal is, as expected, highly contaminated, mainly

by unburnt kerosene. This is why effective filtering is mandatory, as are hygiene

and ease of cleaning.

TROX X-CUBE air handling units are very versatile. They can be individually configured and are hence suitable for a wide spectrum of applications. More than

70 construction variants can handle volume flow rates of 1200 to 86,000 m³/h at

an airflow velocity of 2 m/s. X-CUBE units are available as supply or extract air

units or as a combination of both. Depending on the installation location, they can

be arranged side by side or on top of each other. The cubes are also available for

outside installation on roofs, and thanks to the lifting eyes at the top they can

be easily moved and lifted with a crane. This simplifies installation and reduces

the installation time considerably.

The duplex powder coating (corrosion protection class C4) and the stainless steel

condensate drip tray, which is sloped on all sides, ensure optimum corrosion

protection. Ease of operation and cleaning are further advantages. As an option,

the X-CUBE units can be fitted with high-efficiency activated carbon filters for the

separation of kerosene mist. Heat recovery systems and EC fans ensure high energy

efficiency. The units are available with an integral measurement and control system

upon request. And last but not least, they can of course be integrated with various

building management systems.

TROX TLT X-FANS ventilation fans can be perfectly adapted to diverse ventilation requirements. Whether large or small airflows – or even extract air from commercial

kitchens –, TROX TLT offers a suitable fan. Just go to the configurator software at

Air management: control strategies

The functional areas of an airport are usually divided into different 'control zones'.

Volume flow controllers react to the air quality and adapt the volume flow rate

for every zone separately and based on demand, while frequency converters control

the fan speed, again based on demand. This saves valuable energy and reduces

the 'air transport cost' considerably.

The control strategy of the air handling unit for the base load of an airport depends

on an adjustment of the volume flow rate in relation to the air quality. With an

air-water system the temperature is controlled separately by water side systems.

Only for peak loads is volume flow control included in the overall control of the

room temperature.

Intelligent TROX control systems ensure that all TROX air conditioning components,

including the air handling unit, complement each other perfectly. Components,

units and systems from a single source reduce the design and coordination effort

considerably.

VARYCONTROL VAV terminal units such as TVR/TVT are fitted with electronic controllers. Customers have a choice of many different control components to suit

each situation, be it for integration with the central BMS or to safely shut off fire

compartments (power off to close). The temperature and/or quality of the room air

can be individually adjusted by changing the supply air flow rate. The system only

supplies the amount of air required, which saves energy.
